She was born Viola Katherine Clemmons in Scott County, Illinois. Her father Seldon Perry Clemmons was thirty-one, and her mother Martha Isabell Kilpatrick was twenty-nine. Seldon worked in retail running his own company called "S. P. Clemmons" and her mother Martha was a homemaker. In Katherine's first years of life, she was raised in Montezuma, Pike County, Illinois. Katherine was the couple's third child. Their oldest daughter was named Ella May. Seldon and Martha would later have Ida Susan. Sadly Ida died young, at the age of six. Katherine's parents later divorced when she was still young. After the divorce, the two surviving children went to live with their father. In 1876, they went to live with their mother Martha, who had married Judge Walton Dayan, a stationer for the Southern Pacific Railroad. Occasionally, Katherine and Ella would visit their father and eight half-siblings. In 1891 Katherine, Ella May, Martha, and Walton moved to 449 Seneca Street in Palo Alto, California. Walton and Martha lived there until 1916.
Acting career
Katherine went by the stage name of "Katherine Dayan". Some of her first acting appearances were made at Maguire’s Opera House in San Francisco. Later, Katherine acted in a play called A Lady of Venice starring as a woman called "Nina", first in New York City, and then in Boston. The play was bought by Buffalo Bill. According to one newspaper columnist's review, Katherine had a "beautiful profile and a lissome figure but was devoid of any acting ability".
Relationship with Buffalo Bill
Katherine first met Bill at one of his shows in England. Bill at first had doubts about Katherine and in a letter to Frank Butler emphasized that "She is too swift and dishonest for me". But Bill later recanted his views on Katherine and called her "the finest looking woman in the world". However, when asked about her relationship with Buffalo Bill by the media, Katherine stated that "he was only her dramatic agent and as such had advanced her no funds that had not been repaid". Later in divorce court, her husband Howard Gould accused Katherine of improper conduct with Bill while Katherine and Howard were still married.
Marriage to Howard Gould
Katherine traveled to England in 1891, and there she met Howard Gould. After four years of courtship, they announced their engagement in June 1895. His father, Jay Gould, disapproved of his son's wish to marry Katherine and threatened to take away his son's inheritance. This was not enough to dissuade Howard, and the couple wedded on October 12, 1898, in a private ceremony held in Clemmons' apartment at the Holland House. The low-key reception was at Katherine's request; knowing how ferociously her father-in-law disapproved of their marriage. The wedding cost Howard Gould $5,000,000 out of his inheritance. The marriage itself lasted for less than a decade. Howard accused Katherine of adultery with Dustin Farnum and Buffalo Bill. The couple lived separate lives for several years before the divorce was finalized in 1909. Howard had to pay Katherine $36,000 per year in alimony. It was the largest alimony settlement at the time.
Later years
After the divorce, Katherine spent much of her leisure days raising thoroughbreds on Blue Gap Farm in Boonsboro, Virginia near Lynchburg. In 1910 Katherine was convinced that someone had tried to poison her three times; however, the doctor found no signs of poison in her system and her physician diagnosed her with "extreme nervousness". She died at the age of sixty-one after an illness of several months at Blue Gap Farm on October 24, 1930.
